It may be that the modules re-load in the wrong order on a warm reboot. 
The work-around for this is to remove ( modprobe -r ) and reload the 
modules in your /etc/rc.d/rc.local (or equivalent) script, which runs 
*last* on a reboot.
Modprobe will not unload a module which is used by a 'higher' module. 
The command is ignored, so you need to 'ring the changes' to find and 
remove each one, from the 'top' in whatever order they happen to end up in.
It needs 7 commands to cover all possible orders for 3 modules.

modprobe -r A    A   A
modprobe -r B    B       B   B
modprobe -r C    C   C   C       C   C
modprobe -r A            A   A   A
modprobe -r B        B           B   B
modprobe -r C                C
modprobe -r A                        A

Then reload in the correct order.

PS. I am using an HVR2250 which exhibits this problem. It is race-type 
condition where firmware loading takes too long to complete or the 
modules do not wait for their dependency to be loaded.
It *is* a great PCI-E based tuner. It just needs some 'understanding'.

No I did not get a T-shirt when I obtained 'understanding',

PPS And I am using a USB HVR950 here at work, using a 6 inch antenna to 
receive OTA broadcasts of the World Cup over CBC. It is a great little 
unit and does not exhibit any dis-orders.
This is fed to the 'development and testing' mythtv setup on the desktop 
box. Purely for research purposes, of course. Watch you don't trip over 
the coax cable when you leave the room!
